A NOTE ON INSTALLATION
This unit may be installed on any stable surface.
Since its power transformer (near the left-rear corner)
generates a magnetic hum field of moderate strength,
an LP turntable should not be located directly
to its left.
CAUTION: To prevent a fire or shock hazard, do
not permit this product to become wet. If liquid is acci
dentally spilled on or into it, immediately shut off its
power and unplug the AC power cord. The tuner
should be examined by a service technician before
power is applied to it again.
Do not open the tuner, or attempt to modify or
repair it yourself. Refer all servicing to a qualified
technician.
WARNING TO
UK
USERS. If this apparatus is not
fitted with a UK three-pin plug, do not attempt to insert
the attached plug into a UK mains socket. Instead, cut
the plug from the mains lead and attach a fused UK
three-pin plug using the following safety advice on
wiring.
IMPORTANT.
The wires in this mains lead are
coloured BLUE and BROWN;
BLUE:
NEUTRAL
BROWN: LIVE
The colours of these mains lead wires may not
correspond with the coloured markings identifying the
terminals in your plug. In this case the BROWN wire
must be connected to the terminal which is marked
L(ive) or coloured RED. The BLUE wire must be con
nected to the terminal marked N(eutral) or coloured
BLACK, No connection should be made to the termi
nal marked E or coloured green or green and yellow.
REAR PANEL CONNECTIONS
1. FM ANTENNA INPUT
The FM antenna input socket is designed to accept
a 75-ohm "co-axial" cable. If you want to connect an
antenna with a 300-ohm twin-lead wire, use the sup
plied 300-to-75 ohm balun" adapter. [Fig.1].
Some type of FM antenna must be connected to
the tuner. A ribbon-wire "folded dipole" antenna and a
balun adapter are included to get you started. When
you unfold the ribbon-wire antenna you will note that it
is in the form of a T. The "crossbar" portion of the T
should be stretched out horizontally and tacked in
place (on a wall, on the back of a cabinet, or on the
ceiling). The "vertical" section of the T goes to the
antenna input. Connect
its
two wires to the screw ter
minals on the balun adapter; then plug the balun into
the receiver's FM input socket. [Fig. 1].
2. AM ANTENNA TERMINALS
An external antenna will be needed for AM recep
tion. For most local broadcasting stations a simple
wire up to one meter (three feet) in length will provide
ample signal strength, and such a single-wire
antenna is included with the tuner.
(To
use any other
wire, strip off 1 cm of insulation from one end, and
twist together the exposed wire strands.)
Connect the bare end of the wire to the AM
terminal, as follows; push down the plastic tab below
the AM terminal, this opens the small hole
in the cen
ter of the terminal. Insert the bare wire into the hole
and pull the tab back up to its normal horizontal posi
tion against the body of the terminal. The terminal will
grasp the wire
aric fold
it fl
place. Eig.
The remainder of the antenna may be allowed to
hang down behind the tuner or may be tacked in
place along the rear of a wooden (not metal) shelf (a
metal shelf may interfere with reception. In this case
the wire should be stretched out along the wall away
from the shelving and tacked in place.) Experiment
with the orientation and length.
3. OUTPUT
Connect a stereo patch cord from the Left and
Right output jacks to the corresponding Tuner input
jacks on your amplifier.
4. NAD
LINK
INIOUT
The NAD Link IN connector on the Model 412
allows the tuner to be operated by external control
signals passed from another NAD remote control
model featuring NADLInk, eg. 502 CD Player. A
system remote control will be required as an
accessory. Connect a cable from the master unit Link
OUT (eg. 502) to the NAD Link IN jack on the 412.
The NAD link OUT connector allows remote-con
trol commands to be relayed from the 412 to other
products equipped with a NAD-Link (or compatible)
input. For example you can operate a CD player,
cassette recorder, and this tuner from a single-system
remote control. Connect a cable from the tuner's
NAD Link OUT socket to the NAD Link IN jack on
5. AC POWER CORD
Plug the AC line cord into a "live" wall socket or
into a heavy-duty extension cord.
FRONT PANEL CONTROLS
1. POWER
Press this button to turn on the power. The display
will illuminate. To switch the power off, press the
Power
button again and release it.
In the off position the unit is still connected to
the
mains. Disconnect the power cable when the unit is
not to be used for a long time.
2. MONO
The MONO button disables the stereo FM circuits,
so that all broadcasts will be received (and recorded)
in mono. When listening to distant FM stations, use
the MONO mode to cancel the hiss and distortion
that accompanies a weakly received stereo signal.
Remember to disengage the MONO mode when you
want to receive a local broadcast in stereo.
3. BLEND
The Blend circuit reduces noise in weak FM stereo
signals by reducing the stereo separation.
